On my old phone I had an issue with the proximity sensor and front facing camera. This led me to holding my phone backwards to take photos and being unable to hang up phone calls.
I think I put up with this for a year and a half.
I did end up figuring out the issue with the proximity sensor but opening up my phone to reconnect the camera module was too much effort for me.
Some 20 years ago, the right shift key on my keyboard was busted. I ignored it for so long that I got used to only using the left shift key. To this day, and many keyboards later, that’s still how I type.
